Intro Variable stars are important in astronomy because they provide information on the properties of the stars. Variable stars vary in brightness over time and have periods ranging from a couple hours to hundreds of days. Moreover‚ pulsating stars are variable stars and have two types of pulsating stars‚ such as RR Lyrae and Cepheid. Additionally‚ the simulators in this lab gives individuals a visual model of how variable stars are determined and measured. Therefore‚ the simulators will give individuals
